Prevalence of microplastics in the ocean in Latin America and the Caribbean

The release of microplastics to the ocean is an increasing global environmental concern. The specific characteristics of the Global South (e.g., widespread mismanaged waste and wastewater) make this an even greater challenge. The current study performed a critical review related to the prevalence of microplastics in the ocean in Latin America and the Caribbean, analyzing also the possible sources of microplastics release to the marine environment. A majority of the studies assessed point towards mismanaged waste, inland or offshore, as well as mismanaged wastewater as critical sources of plastic pollution into the ocean. However, there is a need to delve into the effects that these microplastics are generating on local biota and human health.

Automated summary

The release of microplastics to the ocean is a global environmental concern, particularly in the Global South. This study critically reviewed the situation in Latin America and the Caribbean and identified mismanaged waste and wastewater as major sources of plastic pollution in the ocean. However, further research is needed to understand the impacts of these microplastics on local biota and human health.
